Vakumobil - 411002
Description
Our Vakumobil was developed for the extraction of gases from the ground. E.ON Ruhrgas AG Essen had a study carried out, entitled: „Studies on improving the localisation of leakages in cohesive grounds under closed surfaces“
Two points are highlighted in the summary of the report:
- The Esders Vakumobil has a markedly improved suction power compared to conventional technology.
- The low pressure in the surface generated by one suction probe has an impact over several metres. This creates only a movement or distortion of the gas accumulation but not there elimination.
Use in methane emission quantification in accordance with EU Regulation
With the entry into force of the new EU Methane Emissions Regulation, the systematic detection and reduction of methane leaks is becoming increasingly important. In combination with the Laser HUNTER, the Vakumobil provides a practical solution for quantifying methane emissions directly at underground gas pipes. With the help of several ground probes, the soil air is extracted in a targeted manner and then analysed. The gas concentration and the volume flow of the extracted air form the basis for calculating the leak rate according to DVGW G 425-2. This method is particularly relevant for network operators who want to implement an efficient and standard-compliant LDAR strategy even before the legal requirements come into force in 2026.
